IPC: G02F1/13
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal panel without damaging and preventing dust from sticking to the panel, whose display quality is not influenced even if it is damaged or dust sticks to it and in which local temperature elevation due to irradiation of light from a light source can be suppressed, and to provide a projection type display device utilizing it and a method for manufacturing the panel. SOLUTION: A liquid crystal panel 1 is surrounded by a light shielding frame 120 and its outside face is covered with a transparent resin layer 110 packed inside the frame 120. Then, the liquid crystal panel 1 is not damaged and dust does not stick to it. Besides even if a surface of the transparent resin layer 110 is damaged or dust sticks to it, they are not projected on a projection screen since they are in a defocused state. Moreover there is little temperature elevation in the liquid crystal panel 1 since the panel 1 has larger heat capacity equivalent to the formed transparent resin layer 110. Additionally since the transparent resin layer 110 has a refractive index equal to those of a TFT array substrate AM and a counter substrate OP, there is no reflective interface at either of the interfaces between the transparent resin layer 110 and the TFT array substrate AM and between the transparent resin layer 110 and the counter substrate OP.
